PHOTOGRAPHIO CAMERA.

SPECIFICATION forming part of Letters Patent No. 769,319, datedSeptember 6, 1904. Application filed October 14, 1903. Serial No.176,994. (No model.)

To (l/ZZ whmnit 772/6LZ/ concern.-

Be it known that I, MAGNUs NIELL, a subject of the King of Sweden andNorway, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedPhotographic Camera, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in photographic cameras, anobject being to provide a camera of novel form and construction and of asize to be readily carried in a vestpocket.

A further object is to provide a novel filmstrip holder, with means foroperating the same to move the strip, whereby new or unexposed surfacesare brought to exposure position.

I will describe a photographic camera embodying my invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of a photographic camera embodying my invention.Fig. 2 is a section on the line 00 a of Fig. 1. Fig. 3 is a section onthe line y y of Fig. 2, and Fig. 4 is a sectional detail showing therecording mechanism employed.

Referring to the drawings, 1 designates the casing of the camera, whichis substantially in the form of a watchcase, and, in fact, is designedto simulate a watchcase. At one side the casing is provided with aremovable cover 2, and on its periphery it is provided with a lens-tube3 in the form of a watchcasestem, and in this tube is a lens 4, and theouter end of the tube is provided with a removable cap 5, and connectingwith the tube is a ring 6. Movable across the opening of the lens 4 is ashutter consisting of a segmental plate 7, having an opening 8 andmovable between the inner surface of the casing and a plate 9 within thecasing.

Extended inward from one end of the shutter and through a slot 10 in theinner plate 9 is a lug 11, to which one end of a curved rod 12 isattached. This inner plate 9, it Will be noted, has an opening 13 inline with the lens-tube opening. The rod 12 passes loosely through anopening in a lug 14, extended inward from the plate 9, and it alsopasses loosely through a slot formed in a latch-plate 15, designed toengage with either one of the shoulders 16 17, formed on the rod. Thislatch-plate is attached to a spring-plate 18, from the free end of whicha finger-piece 19 extends outward through an opening in the casing.Surrounding the rod 12 is a spring 20. This spring bears at one endagainst a collar 21 on the rod adjacent to the lug 11, and at the otherend the said spring engages with the lug 14. The object of this springis to move the shutter to closing position, as will be hereinafterdescribed.

The shutter has at one end a lug 22, which extends outward through anopening 23 in the periphery of the casing. Extended transversely in thecasing is a partition 24, provided with an exposure-opening 25, whichobviously is in line with the lens. The said partition forms one wall ofa chamber 26, in which the holder or magazine for the sensitized stripor film is placed. These holders, with the strips thereon, are designedto be purchased as a complete article, whereby a new one may be placedin the camera when all the surfaces of a previous strip shall have beenexposed. In order to be able to load and unload the camera in daylight,the ends of the film-strip are made lightproof.-

The holder comprises upper and lower plates 27 28,'connected at thefront by a plate 29, over which the sensitized strip passes, the saidplate 29 being rearward of the opening 25 and opposite the partition 24,and the said plates 27 and 28 are connected by a narrow post 30. Thesaid plates 27 and 28 are provided with inwardly-extended tubular lugs31 32, which may be formed by pressing in portions of the plates. Theselugs form bearings for the take-up spool 33 and the let-01f spool 34.Arranged within the spool 33 is a cross-pin 35, designed to engage in anoutwardly-opening notch formed in a spindle 36, l which extends outwardthrough the bottom or back plate of the casing, where it is providedwith a turning-handle 37, it being understood that the said spindle hasrotary n10- tion. This spindle not only has a bearing in a wall of thecasing, as above described, but also has a bearing in a plate 38, whichforms the base upon which the film-strip holder rests. Extended inwardfrom said plate 38 is a short pin 39, designed to pass into the spool34, which, with the spindle 36, holds the film-strip holder in properposition in the chamber 26. It will be noted that the spool 34 has across-pin similar to the crosspin in the spool 33. This is forconvenience in manipulating the parts when the film is first placed inthe holder, and it is not in any manner engaged with the said pin 39.

Mounted to rotate between the plate 38 and the adjacent wall of thecasing is a tally or recording wheel 40. This wheel is provided withnumbers 41, designed to be seen consecutively through a sight-opening42, formed in the casing-wall, the numbers of course being designed toindicate the number of exposures made. The wheel 40 is provided withperipheral teeth 43, designed to be engaged by a finger 44, connected tothe spindle 36.

In the operation when it is desired to make an instantaneous exposurethe shutter is to be moved until its end or the lug 22 engages againstthe end of the slot 23. Then after removing the end of the cap 5 thefinger 19 is to be pressed inward, releasing the shoulder 16 of the rod12 from the plate 15. Then the compressed spring 20 will move theshutter toward its closed position, and when its opening 8 passesrapidly across the lens-tube the exposure will be made. Before theexposure of course the film-spools must be turned until the numeral O isseen through the opening 42. When the next exposure is to be made, theturning-handle 37, connected with the spindle .36, carrying the spool33, is to be turned onehalf a revolution, which will bring a new. partof the film-strip into exposure position. The size of the spool 33 issuch that its circumference is equal to double the size of theexposure-opening 25 'in the partition 24. The turning of the handle 37also imparts movement to the wheel 40, thus bringing a new numeral intoview, indicating the number of exposures. \Vhen a time-exposure is to bemade, the shutter is to be moved until the shoulder 17 engages with thelatch-plate 15.

At this time the opening Swill be in line with the lens-tube opening.Upon removing the cap 5 the exposure will be made for the desired lengthof time, and then upon pressing the finger-piece 19 the shutter will bemoved to close the opening. The spindle 36 is .prevented from backwardrotation by means of a spring 45, arranged in the path of the arm 37.This spring is pressed out of the metal forming the casing in suchmanner as to permit the arm 37 to pass readily over it when moving inthe right direction.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A photographic camera comprising a cir cular casingclosed at the top and bottom, a lens-holder extended from the peripheryof the casing, a film-holder in the casing consisting of opposite platessecured together, spools mounted to rotate between the plates, a spindleextended through a wall of the casing and engaging with one of thespools, the said wall of the casing having a sight-opening,arecording-wheel in the casing and having numerals adapted to be seenthrough said opening, and means carried by the spindle for impartingrotary motion to said wheel.

2. A photographic camera comprising acasing, a lens arranged in theperiphery thereof, a shutter movable across said lens,,a filmstripholder comprising opposite plates having inwardly-extendedtubular lugs,said plates being connected at opposite edges,

spools mounted to rotate on said lugs, one of said spools having aninterior cross-pin, a spindle passing into the casing and having aslotted end to receive said pin, a recording device operated by thespindle, and a turningfinger on the outer end of said spindle.

3. A photographic camera comprisinga casing. a lens and a shuttertherefor, a film-holder comprising opposite plates secured together attheir opposite edges, lugs extended inward from said opposite plates,spools mounted to rotate on said lugs, a cross-pin arranged in one ofthe spools, a spindle extended through a wall of the casing and having aslotted end for receiving said pin, the saidwall of the casing beingprovided with a sight-opening, a recording-wheel arranged in the casingand having numerals adapted to be seen through said sight-opening,peripheral teeth on said wheel, and a finger on said spindle for engaging with said teeth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
